I thought that was where things were heading after the cliffhanger and I saw the Gold Ranger toys. But I am glad we ultimately ended up with Jason as well. I didn't love Trey. But it was an original idea at the time.

Not per see. He was kind or a macguffin in the beginning. As he was the destination of Tommy's arrowhead mystery. Which started on his Zeo Quest. Than when he went on his vision quest in Zeo, he found out he had a long lost brother.

David was really just a guest star for two episodes. His biggest role was in the two part Zeo episode that bookended the summer hatius. Where Tommy meets him and learns about how they each have half an arrowhead that is the key to ancient monsters. Mondo captures David to get the other half of the arrowhead. Tommy has to master the Red Battlezord to save him. After that he had a bit role in an episode with the Rangers surfing. Its teased that he has been very busy lately. As some sort of Gold Ranger Red Herring. But nothing ever comes of it and we never see him again on the show

David was actually played by JDF's real like brother, Erik. Unfortunately Erik Frank ended up passong away from an ilness years later.
